volatile

-The volatile keyword can be applied to fields of these types:
-Reference types.
-Pointer types (in an unsafe context). Note that although the pointer itself can be volatile, the object that it points to cannot. In other words, you cannot declare a "pointer to volatile."
-Simple types such as sbyte, byte, short, ushort, int, uint, char, float, and bool.
-An enum type with one of the following base types: byte, sbyte, short, ushort, int, or uint.
-Generic type parameters known to be reference types.
-IntPtr and UIntPtr.
